Study Groups

Psoriatic arthritis
Patients with psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis (CASPAR).
Disease activity in psoriatic arthritis (DAPSA)
DAPSA includes a 68/66 joint count summed with a patient global, patient pain score, and C- reactive protein level. The DAPSA provides a continuous score of arthritis activity and has validated cut points for remission (\< 4) and low disease activity (\< 14).
Compliance-Questionnaire-Rheumatology (CQR)
The CQR is a self-administered questionnaire that was developed with the aim of correctly identifying patients that were classified as "low" adherers (taking \<80% of their medication correctly). The four point Likert answering scale ranges from; "Definitely don't agree" (scored 1) to "Definitely agree" (scored 4) with lower scores indicating lower levels of adherence. Total score is between 0 and 100.
The Brief Illness Perception Questionnaire (BIPQ)
The Brief Illness Perception Questionnaire (BIPQ) is a questionnaire that assesses a number of beliefs about illness which are thought to be related to coping and help-seeking behavior. Each item is scored between 0 and 10. Maximum total score is 80. Higher scores represents that the patient has a concerned perception of illness.
The Beliefs About Medicines Questionnaire (BMQ)
The Beliefs About Medicines Questionnaire (BMQ) is a tool for evaluating people's beliefs about medicines. The BMQ comprises two sections: the BMQ-Specific which assesses representations of medication prescribed for personal use and the BMQ-General which assesses beliefs about medicines in general. It has a total of 18 questions scored with a 5-point Likert scale. Higher scores represent more powerful beliefs.
Hospital Anxiety and Depression Scale (HADS)
Hospital Anxiety and Depression Scale (HADS) determines the levels of anxiety and depression that a person is experiencing. The HADS is a fourteen item scale that generates: Seven of the items relate to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 and 21 for either anxiety or depression.
The Psoriatic Arthritis Quality of Life (PsAQoL)
The Psoriatic Arthritis Quality of Life (PsAQoL) measure is a disease specific patient-reported outcome measure which measures the effect that psoriatic arthritis has on a patient's quality of life. It is a self-administered, 20-item questionnaire that takes about three minutes to complete. The answers are restricted to true or false.A high score on the PsAQoL indicates a lower quality of life. Total score is between 0 and 20.
